In the prior art, at present, the integral structure of the vibrating diaphragm 06, the support 04 and the sealing ring 03 is generally molded directly by injection molding, and then the molded structure is directly subjected to blanking, but when the injection molding is just finished, the integral structure is still higher in temperature and is not completely cooled, so that the integral structure is easy to deform, particularly the vibrating diaphragm 06 is used for an audio vibration structure, is particularly thin, and can be deformed due to slight contact under the uncooled condition, even if the slight deformation can influence the vibration effect of the vibrating diaphragm 06, the sound quality is influenced, and therefore, when the injection molding is just finished, the integral structure is not contacted, and meanwhile, the structure is rapidly cooled, so that the influence on the vibrating diaphragm 06 in the subsequent processing is reduced;
when in processing, the driving device firstly moves the upper die 18 to the position of the lower die 23, the upper die 18 and the lower die 23 form a finished die, an injection cavity 32 is formed inside the upper die 18 and the lower die 23, at the moment, injection molding is carried out into the injection cavity 32 through an injection molding machine (the prior art), a structure formed by integrating the vibrating diaphragm 06, the support 04 and the sealing ring 03 can be directly formed through the injection cavity 32, then the driving device drives the upper die 18 to be far away from the lower die 23, at the moment, the air pipe 19 can generate negative pressure, so that all the suction pipes 20 generate negative pressure, therefore, the upper die 18 is far away from the lower die 23, the vibrating diaphragm 06, the support 04 and the sealing ring 03 can be driven by the suction pipe 20 to be integrally formed, meanwhile, the negative pressure of the air pipe 19 can enable air to continuously enter the suction pipe 20, so that heat generated by the integral structure sucked at the lower end of the suction pipe 20 can be taken away along with the air pumped in by the suction hole 28, and the cooling function of the structure can be realized rapidly;
compared with the prior art, firstly, the air pipe 19 enables the suction pipe 20 to generate negative pressure, the suction pipe 20 can suck a formed structure when injection molding is finished, the suction pipe can move out of the lower die 23 along with the suction of the upper die 18, thereby realizing blanking, direct blanking in modes of clamping or direct shaking and the like, direct contact of the suction pipe 20 to the formed structure is greatly reduced, the problem that the suction pipe 20 is easy to deform because of temperature is reduced, in addition, part of air can flow into the suction pipe 20 through the suction hole 28, the air pipe 19 enables the suction pipe 20 to generate negative pressure, if pressure release of the suction hole 28 is not carried out, suction force in the suction pipe 20 is overlarge, thus causing slight deformation of the insufficiently cooled formed structure to the suction pipe 20 due to the suction force of the suction pipe 20, meanwhile, the air around the inner wall of the upper die 18 can be quickly introduced into the suction pipe 20 through the suction hole 28, the rapid suction heat of the just formed structure is quickly pumped into the suction pipe 20 through the air pipe 19, the rapid forming structure is realized, the structure is simultaneously realized, the structure is cooled through the air pipe 19, and the cooling function is realized, and the cooling cost is low.

The electric cylinder drives the screw rod 13 to rotate, the screw rod 13 can enable the sliding seat 14 to slide on the sliding frame 12 when rotating, so that the sliding seat 14 can push the hanging rod 17 to move simultaneously by pushing the round shaft 26, at the moment, the round shaft 26 cannot slide downwards along the sliding groove of the pushing groove 15 due to the limiting function of the guiding rail 31, so that the round shaft 26 can only slide linearly along the guiding rail 31 in the horizontal direction until the round shaft moves to the leftmost end of the guiding rail 31, at the moment, because the left end of the guiding rail 31 extends downwards, at the moment, when the sliding seat 14 pushes the round shaft 26, the round shaft 26 can slide downwards along the pushing groove 15 along with the continued leftward movement of the sliding seat 14, so that the round shaft 26 can slide downwards along the left end of the guiding rail 31, and at the same time, the round shaft 26 can simultaneously drive the hanging rod 17 to move simultaneously when moving, therefore, the suspension rod 17 drives the upper die 18 to move linearly and then move downwards, when the upper die 18 moves downwards, and when the round shaft 26 moves to the lowest part of the leftmost end of the guide rail 31, the upper die 18 just coincides with the lower die 23 vertically to form the injection cavity 32, and due to self-locking property of threads, when the electric cylinder does not rotate, the slide seat 14 cannot slide on the slide frame 12, so that the position of the upper die 18 cannot deviate, the upper die 18 and the lower die 23 can be ensured to continuously form a finished die, then the injection molding machine (prior art) can perform injection molding into the injection cavity 32 until the whole injection cavity 32 is filled, so that the forming process is finished, and after the injection molding is finished, the screw rod 13 rotates reversely, the slide seat 14 is driven to perform reset movement, so that the suspension rod 17 firstly drives the upper die 18 to move linearly upwards, then moves straight to the right, thereby driving the upper die 18 to move to the right out of the position of the lower die 23;
because the guide rail 31 is the frame-shaped structure, the position of the circular shaft 26 is always fixed, so that the precision is higher, the processing of the small waterproof horn with high precision requirement is more suitable, and the formed structure can be sent away from the processing position through the guide rail of the guide rail 31, so that the blanking is convenient, and therefore, enough time is available for the suction hole 28 to absorb heat and cool in the blanking process.
As a further aspect of the invention, the adjusting means comprises a spring provided on the boom 17 to move the air pipe 19 in a direction approaching the machine tool 11, and a limit lever 22 fixedly attached to the machine tool 11 to move the air pipe 19 upward.
When the upper die 18 is at the rightmost end of the guide rail 31, the spring on the hanging rod 17 pushes the air pipe 19 to move downwards on the upper die 18, so that the suction pipe 20 can extend downwards from the upper die 18, then the air pipe 19 starts to descend along with the movement of the upper die 18 to the leftmost end of the guide rail 31, when the air pipe 19 moves to the position of the limiting rod 22, the limiting rod 22 can prop against the air pipe 19, so that the air pipe 19 cannot move downwards along with the upper die 18, the spring is compressed, then the upper die 18 continues to move downwards and the lower die 23 form a complete die, when the upper die 18 and the lower die 23 are overlapped, the lower end face of the suction pipe 20 and the inner wall of the upper die 18 are just at the same level, meanwhile, the air nozzle plug 30 and the suction nozzle 29 are overlapped, the lower end face of the air nozzle plug 30 and the lower end face of the suction pipe 20 are also at the same level, and the part of the suction pipe 20, which is provided with the air suction hole 28, can be all above the upper surface of the upper die 18, and injection molding can be performed at the moment;
the principle of injection molding is to inject plastic slurry into a closed cavity under a certain pressure so as to form the plastic slurry, so that the mold is required to be sealed, when the upper mold 18 descends and the lower mold 23 coincide, the lower surface of the suction pipe 20 and the inner wall of the upper mold 18 coincide at the moment, meanwhile, the air nozzle plug 30 coincides with the suction nozzle 29, so that the inner wall of the upper mold 18 is completed and smooth, the injection molding process is ensured to be carried out, the suction pipe 20 is not subjected to negative pressure and cooling functions, the injection molding function is not disturbed, when injection molding is carried out, the air pipe 19 is pushed to move downwards along with the reset spring of the upper mold 18 driven by the suspension rod 17, so that the suction pipe 20 stretches out to the lower side of the upper mold 18 again along with the ascending of the upper mold 18, at the moment, the upper mold 18 can push the forming structure out of the upper mold 18 at first, so that the demoulding process of the forming structure is realized, and a gap is formed between the forming structure and the inner wall of the upper mold 18, so that air flow can circulate, and the suction air of the suction hole 28 is not disturbed, so that the cooling function of the forming structure is realized.
